Application December 8, 1934, Serial No. 756,642

Claims. (Cl. 20-40) My invention relates to windows for solar bathing, and especially to nude all year sun bathing; and the objects thereof are to provide a window adapted for installation in dwelling houses and 5 constructed so that the nude bather may be exposed to the full rays of the sun or to the ultraviolet rays as transmitted through special glass and at the same time be screened from outside view, and in cold weather from the outside cold.

I attain these objects by the special construction and mechanism illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of the win-dow as tilted outward; Fig. 2 a horizontal section on line 2--2 of Figs. 1 and 3; Fig. 3 a vertical section on line 3--3 of Fig. 1, showing the window set flush with the house wall; Fig. 4 an enlarged fragmentary section of Fig. 3; Fig. 5 shows a modication of Fig. 3 in vertical section with the window set outward from the house wall; and Fig. 6 a fragmentary horizontal section in line 6-6 of Fig. 5.

It is well known that ultraviolet rays derived from the sun produce certain health giving vitamins in the body and that common window glass and clothing screen out these invisible rays, therefore I have provided mechanism to allow full sun exposure to nude bathers or a reduced ultraviolet transmission through special glass, as the conditions require, together with means for excluding sight from outside.

In the following description reference is had to the drawings in which similar numerals denote similar parts throughout the several views:

The numeral I denotes the sunny side of a house wall; 2 the outwardly tilted window sash glazed with special ultraviolet transmission glass; 3 the flexible fabric end closures; 4 are the tapered rollers, having a spring 4a mounted in the core thereof, upon which the fabric closures are rolled as the sash assumes the closed upright position; 5 a rigid closure fixed to the sash and adapted to enter the pocket below the fabric as the sash cioses; 6 a cable xed to the sash and adapted to be wound upon the spool l, one at each end of the shaft 3 which is rotated by the spring S. This spring is so tensioned as to control or balance the weight of the tilted sash, and

the spring of the roller Il is tensioned to Wind the fabric closure upon,this roller; the pocket cover I0 will enclose and conceal the rollers and fabric when the window is closed and the pocket II covers the shaft 8 and spring 9. The sash is pivoted or hinged at I2 and locks with a pole catch at I3 when closed. In tapering and mounting the spring actuated roller II, it is necessary that the axis and taper lines, if extended downward, shall converge at the center line of the window pivot or hinge, but since it is impracticable to continue the roller to an absolute point, I truncate the cone and locate a bearing on the axis line at top of the closure 5 as shown; a roller tapered and revolubly mounted in this manner will wind up the triangular fabric in an even lo tapered roll.

In operation: The patient desiring a sun bath with full exposure, tilts the window outward as shown, allowing the full sun rays to enter the opening, then he reclines upon a couch placed to lo receive the sun rays as at I4, when such couch is exposed to outside view the curtain I5 may be raised sufficiently to screen the bather. On a very hot day when the full sun rays are too strong or when the weather is too cold for the wide opengg ing, the sash may be partly closed so that the sun rays will fall through the glass whereby the bather will receive a reduced transmission of the ultraviolet rays and still retain a comfortable temperature and ventilation, other ventilation 25 may be had through the small sash IB.

The above description of the mechanism and construction applies particularly to Figs. 1, 2, and 3 where the window is set flush with the house wall and the end closures are made to wind up in 30 shallow pockets so as not to project into the room. In Figs. 5 and 6, is shown a modification, omitting the fabric closures and their rollers and substituting triangular rigid end closures Il, and

Vsetting the window outward so as to deepen the 35 pocket I8 and cover Ia suflicient to receive the rigid closures, otherwise both types are similar.

Having thus clearly described my invention, what I claim as new and desire to secure by Letters Patent is 40 1. A solar bathing window, consisting of a window set in the wall cf a house structure, the sash of which is pivoted at the bottom and adapted to tilt outwardly, said sash having fabric end closures adapted to roll up on tapered rollers and be concealed in pockets while the sash is in closed position, and means for balancing weight of the tilted sash.

2. A solar bathing Window, consisting of a 50 bottom pivoted outwardly tilting sash having triangular fabric end closures fixed thereto, means for rolling up and concealing said closures and means for balancing the weight of said sash when outwardly tilted. 55

3. A solar bathing Window, comprising a bottom pivoted outwardly tilting sash having triangular fiexible end closures, tapered spring actuated rollers adapted to roll up said closures, pockets concealing said rollers, spools and cables to balance the Weight of the sash and a spring actuated shaft controlling said spools.

4. In a solar bathing window, a bottom pivoted sash in combination with flexible end closures,

10 truncated taper rollers mounted with the taper lines converging at the center line of the sash pivot and adapted to roll up said exible closures.

5. In solar bathing Windows, the combination of a bottom pivoted sash, with balancing means consisting of a spring actuated shaft mounted parallel with and above the sash, spools upon the shaft and cables xed to the spools and to the sash whereby the Weight of the sash is balanced by the spring.
